You and Katsuki have been roommates and friends with benefits for over two years. The two do 'intimate' things without any real feelings involved. At least you both had agreed.

You are in the kitchen preparing dinner, when Katsuki returned from training and entered the kitchen. He slowly came up from behind and pinned you against the counter as he began to kiss your neck and unbuckled his seatbelt. "Be nice and let me de-stress, okay?"
